Description
Technical field
The present invention relates to document processing technology field, and in particular to a kind of portable common document play system.
Background technology
With the depth development of internet industry, internet enters the Web2.0 epoch comprehensively, and it brings more
More opportunities and challenges, many traditional client application technologies are applied to internet, such as customer relation management, account pipe
Traditional IT operation systems such as reason system, online picture editor, script making of developer etc. are served for another example and applies skill
Art, emerging the Internet, applications technology emerge in an endless stream.
Conditional electronic document browses, such as the file of POWERPOINT, WORD, TXT, PDF form, existing usual
Way is to install document reading software by computer, is browsed and is operated in a manner of software opens file.
At present, upload and playing function of many websites all with document, website encourage user to upload document, realize data
Mutually enjoy.But mostly the document of website can only be played by a kind of form, user computer or mobile phone must be mounted with to open the lattice
The software of formula could be realized plays document on the net, and use is very inconvenient.
Therefore, in view of the above-mentioned problems, the present invention proposes a kind of new technical scheme.
The content of the invention
It is an object of the invention to provide a kind of a kind of high portable common document of performance easy to use, safe to play system
System.
The present invention is achieved through the following technical solutions：
A kind of portable common document play system, including S3C2440 processors, main memory, deposit instrument chip, image procossing
Module, power module and USB-HUB interfaces, the system is using S3C2440 processors as core, during using SDRAM as system operation
Main storage, using NANDFLASH as operating system memory chip, the S3C2440 processors pass through data wire and master
Memory is connected with memory chip；
The S3C2440 processors are connected with image processing module and USB-HUB interfaces respectively, and electricity is provided with the system
Source module, power module are provided with power interface.
Preferably, described image processing module is engaged with USB-HUB modules.
Preferably, the artwork processing module side sets VGA display interfaces.
Preferably, the USB-HUB interfaces are connected with USB device interface and USB mouse interface.
Preferably, the system uses WONDOWSCE5.0 operating systems.
The beneficial effects of the invention are as follows：System proposed by the present invention overcomes that conventional desktop convenience is bad, and power consumption is big
And the shortcomings that notebook cost is high, security difference, the occasions such as teaching, meeting are can be widely applied to, are a kind of very useful
Presentation tool.
Brief description of the drawings
Fig. 1 the structural representation of present invention.
Embodiment
Illustrate to be described further the present invention below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of portable common document play system, including S3C2440 processors, main memory, deposit instrument
Device chip, image processing module, power module and USB-HUB interfaces, the system is using S3C2440 processors as core, with SDRAM
Main storage during as system operation, using NANDFLASH as operating system memory chip, S3C2440 processors pass through
Data wire is connected with main storage and memory chip；S3C2440 processors respectively with image processing module and USB-HUB
Interface is connected, and power module is provided with system, and power module is provided with power interface, image processing module and USB-HUB moulds
Block is engaged, and artwork processing module side sets VGA display interfaces, USB-HUB interfaces and USB device interface and USB mouse interface
It is connected, system uses WONDOWSCE5.0 operating systems.
In the technical program, the system reads the file content in USB device and decoded, and decoding is completed file
Content is sent to video frequency signal processing chip by 16B display datas port with view data and enters row format conversion, eventually through VGA
Interface shows image.
It is bad that system proposed by the present invention overcomes conventional desktop convenience, and power consumption is big and notebook cost is high, peace
The shortcomings that full property difference, the occasions such as teaching, meeting are can be widely applied to, are a kind of very useful presentation tools.
